Abstract: L'invention concerne un mécanisme distributeur de produits (37), lesquels présentent des surfaces généralement plates et sont soutenus entre une première paroi (47), généralement verticale, et une seconde paroi opposée (49), généralement verticale, de sorte que ces produits (37) sont empilés les uns sur les autres dans une goulotte de stockage (45). Au niveau d'une partie inférieure de cette goulotte (45), se situent une première patte (57) ainsi qu'une seconde patte (59), cette dernière étant espacée de la première et située verticalement plus bas. Une surface de support des produits (53) s'étend en travers du fond de la goulotte (45) et communique avec une ouverture (55) de déchargement ménagée dans la seconde paroi (49). Les produits (37) sont donc soutenus dans la goulotte (45) par la surface de support (53) et la première patte (57), et ils sont distribués par retrait de la première patte (57), ce qui permet au produit situé le plus bas de tomber sur la seconde patte (59). La première patte (57) s'avance pour se placer en dessous du produit suivant situé plus haut dans la goulotte (45), la seconde patte (59) se rétracte alors afin de permettre au produit situé le plus bas de tomber sur la surface de support (53) et de passer à travers l'ouverture (55) de déchargement, les produits restants étant soutenus par la surface de support (53) et la première patte (57). Dans une variante de réalisation, il peut n'y avoir qu'une seule goulotte (45) et plusieurs surfaces de support (53), ainsi qu'une première et une seconde patte (57 et 59), ce qui permet d'empiler plusieurs types de produits différents dans la seule goulotte (45). Dans un autre mode de réalisation, un produit lourd (115) et à surfaces plates est empilé côte à côte, dans le sens de la hauteur, sur un plancher (125) s'étendant généralement horizontalement, mais incliné, le produit se déplaçant horizontalement vers un côté pour être distribué. Une patte (129) est montée au niveau de ce côté, de même qu'une butée mobile (153) des produits. L'espace entre la patte (129) et la butée (153) est généralement égal à l'épaisseur du produit. Ainsi, le produit peut être distribué par retrait de la patte (129), ce qui permet à chaque produit de se déplacer vers ledit côté et au mécanisme d'être prêt à distribuer le produit suivant.

Abstract: The present invention relates to a solid catalyst (D) for olefin polymerization comprising a magnesium-containing solid component (A) carrying thereon an organoaluminum-oxy compound (B) and a metallocene compound (C), the magnesium-containing compound (A) being obtained by heat treating a magnesium compound represented by the general formula: MgX2.cndot.nH2O where X represents a halogen atom and n is an integer of 1 to 12, and to a method of producing an olefinic polymer using the catalyst.      In the case where the above solid catalyst for olefin polymerization is used, catalyst activity, particularly activity per solid catalyst, is high. Therefore, catalyst cost is inexpensive and a deashing treatment step such as catalyst removal can be omitted. Further, the olefinic polymer produced has a narrow molecular weight distribution, and in the case of a copolymer, its monomer composition is uniform.

Abstract: Inflatable harness respiratory apparatus (10) is provided having an improved comfort control assembly (16) allowing reduction in the engagement force exerted by the fitting surface (20) of the mask (12) against the face of the user. The mask (12) is equipped with an inflatable hamess strap element (26) having terminal ends (28, 30) supported on stationary, tubular mask mounts (36) via housing assemblies (38). In one embodiment, the terminal ends (28, 30) are releasably locked onto the mounts (36) by means of locks (52), but are axially shiftable along the length of the mounts (36) in order to adjust the effective distance between the fitting surface (20) and the terminal ends (28, 30). An adjustment button (78) may be depressed in order to disengage the locks (52) and permit shifting of the associated terminal end (28, 30). Alternately, an intermediate comfort position is pneumatically achieved by controlled pressurization of an internal cavity (128) within the housing assembly (88).

Abstract: A fuel-fired heating appliance, representatively a gas-fired water heater, has a combustion chamber in a lower end portion thereof, and fuel burner apparatus having main and pilot burner portions is operatively disposed in the combustion chamber. During operation of the water heater combustion air is supplied to the burner apparatus only via a duct structure having an inlet elevated relative to the floor or other horizontal support surface upon which the water heater rests. A flammable vapor sensor is mounted on the lower end portion of the water heater, externally of the combustion air supply duct structure and at an elevation lower than that of its elevated inlet, and is operatively connected to burner control circuitry which, in turn, is coupled to the burner apparatus.     In the event flammable vapors are generated near the floor adjacent the water heater, the vapor sensor operates to detect such vapors and responsively disables the burner apparatus via the control circuitry. The difference in elevation between the vapor sensor and the elevated combustion air inlet gives the sensor additional time to detect and respond to flammable vapors before they upwardly reach the elevated combustion air inlet.

Abstract: A Down Hole Drilling Assembly (DHDA) is disclosed that induces artificial lift to remove the drilling and production fluid from a well bore during drilling operations by means of a single or multiple hydraulic jet pumps attached to a concentric string of casing. The DHDA includes a drill string and drill bit that passes through the jet pump assembly so that the power fluid is separated from the drilling or production fluid until after it has passed through the nozzle of the jet pump. The jet pump assembly is joined to a concentric casing string. The jet pump also contains a bladder element that inflates or expands to redirect the flow of the drilling and production fluid from the inner or return annulus into the jet pump assembly. The purpose of the jet pump assembly is to artificially lift and remove fluid thereby lowering the fluid level within a well bore to a point where the hydrostatic pressure exerted by the column of fluid near the bottom of the well is lower than the pore pressure of the formation being drilled thereby creating an under balanced condition.

Title: Long-life traveling spark ignitor and associated firing circuitry
Inventor: SUCKEWER ARTUR P
IPC: F02P9/00
Filed: 2000-06-16
Granted: 2009-11-17
Abstract: An ignitor and associated electronics for igniting a combustible mixture in a cylinder of an internal combustion engine are described. The ignitor includes at least two spaced-apart electrodes that define a discharge gap. The space between the electrodes is substantially filled with a dielectric material. The dielectric material is spaced-apart from at least one of the electrodes to provide an air gap over which an initial voltage breakdown between the electrodes will occur. The air gap serves to vary the location of the initial breakdown and as a barrier to a short circuit between the electrodes due to carbon and/or metal deposit buildup on the dielectric material.     The associated electronics provide a first potential between the electrodes that generates a plasma between the electrodes. Then the volume of the plasma is increased by the application of a second potential that creates a current through the plasma. The plasma, as well as the current passing through, is swept outward due to the interaction of Lorentz and thermal expansion forces with the plasma. Also described are relative orientations of the electrodes that lead to greater plasma formation.
